[ANGLÈS] This project details the design, implementation and measures to characterize the hardware for the acquisition of the electrical impedance spectrum. It also includes the signal generation using an arbitrary multifrequency generator, the acquisition and the signal processing. The system is based on a Field Programmable Gate Array (FPGA). An embedded processor has been implemented inside the FPGA, which manages all the other blocks that comprise the system. It also includes hardware design, FPGA programming using VHDL code and predefined blocks and communicating with the computer via the USB port. Finally, measurements were carried out to characterize the system to verify its performance.
